DIGITAL REALTY TRUST, INC. REPORTS SECOND QUARTER FFO OF $1.22

PER SHARE, UP 11.9% OVER SECOND QUARTER 2012

San Francisco, Calif. (July 26, 2013) – Digital Realty Trust, Inc. (NYSE: DLR), a leading global provider of data center solutions, today announced financial results for the second quarter of 2013. All per share results are on a diluted share and unit basis.

Highlights:

1

Funds from operations (“FFO”), on a diluted basis, was $167.8 million in the second quarter of 2013, or $1.22 per share, up 5.2% from $1.16 per share in the first quarter of 2013, and up 11.9% from $1.09 per share in the second quarter of 2012. Excluding certain items that do not represent core expenses or revenue streams, second quarter 2013 core FFO was $1.19 per share, up 0.8% from first quarter 2013 core FFO of $1.18 per share, and up 11.2% from second quarter 2012 core FFO of $1.07 per share.

FFO is a supplemental non-GAAP performance measure used by the real estate industry to measure the operating performance of real estate investment trusts. FFO and core FFO should not be considered as substitutes for net income determined in accordance with U.S. GAAP as measures of financial performance. A reconciliation from U.S. GAAP net income available to common stockholders to FFO, a definition of FFO, a reconciliation from FFO to core FFO, and a definition of core FFO are included as an attachment to this press release.

Net income for the second quarter of 2013 was $59.6 million, compared to $51.7 million for the first quarter of 2013 and $54.0 million for the second quarter of 2012. Net income available to common stockholders in the second quarter of 2013 was $47.1 million, or $0.37 per share, compared to $42.7 million, or $0.34 per share, in the first quarter of 2013, and $42.0 million, or $0.38 per share, in the second quarter of 2012.

The Company reported total operating revenues of $363.5 million in the second quarter of 2013, up 1.4% from $358.4 million in the first quarter of 2013, and up 19.7% from $303.7 million in the second quarter of 2012.

“We are very pleased with our operating performance and second quarter financial results,” said Michael F. Foust, Chief Executive Officer of Digital Realty. “Our leasing volume and pipeline remain robust despite some lease agreements that we expected to sign in the second quarter ultimately being completed in July. We are encouraged by the notably strong rental rates we are seeing across the portfolio for new Turn-Key Flex^SM leases and renewals. We also continue to see strong demand for multi-megawatt, multi-site requirements from our larger enterprise clients, and are positioned to leverage our unique position in the market to capture those opportunities. We remain confident that our operational expertise, scale, global footprint and financial resources continue to enable us to execute on our strategic plan and enhance shareholder value.”

A reconciliation of the range of 2013 projected net income to projected FFO and core FFO follows:

Note Regarding Funds From Operations

Digital Realty calculates Funds from Operations, or FFO, in accordance with the standards established by the National Association of Real Estate Investment Trusts, or NAREIT. FFO represents net income (loss) available to common stockholders and unitholders (computed in accordance with U.S. GAAP), excluding gains (or losses) from sales of property, impairment charges, real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. Digital Realty also believes that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our financial condition and results from operations, the utility of FFO as a measure of our performance is limited. Other REITs may not calculate FFO in accordance with the NAREIT definition and, accordingly, our FFO may not be comparable to such other REITs’ FFO. Accordingly, FFO should be considered only as a supplement to net income as a measure of our performance.

11

Core Funds from Operations

We present core funds from operations, or CFFO, as a supplemental operating measure because, in excluding certain items that do not reflect core revenue or expense streams, it provides a performance measure that, when compared year over year, captures trends in our core business operating performance. We calculate CFFO by adding to or subtracting from FFO (i) termination fees and other non-core revenues, (ii) significant transaction expenses, (iii) loss from early extinguishment of debt, (iv) costs on redemption of preferred stock, (v) significant property tax adjustments, net and (vi) other non-core expense adjustments. Because certain of these adjustments have a real economic impact on our financial condition and results from operations, the utility of CFFO as a measure of our performance is limited. Other REITs may not calculate CFFO in a consistent manner. Accordingly, our CFFO may not be comparable to other REITs’ CFFO. CFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.
